The reason is that the emulator is going to change, and will have a
data structure identical to i387_hard_struct. Therefore, most of the code
for the interface between the debugger and the emulator is not needed.
However, the version of the patch for 2.0 kernels has not been modified.
It continues supporting core dumping FPU registers with the emulator, as
well as ptrace(2) with it. I do not think that the code of the emulator
should change in a 2.0 kernel, that is intented to be stable.
As usual, you can get them from ftp://jl1.quim.ucm.es/pub/ramon
